Tiered storage: IceTier

A distributed object storage on top of disk and tape

The goal of the IceTier project is to build an archival object storage service based on tape storage media.

One use case of a tape based object storage is a standalone service that stores objects directly on tape with disk being optionally used for caching.

In another use case, the “cold” objects from the highly available, disk based, primary object store are migrated to the low-cost tape-based object storage.

In yet another use case, disk and tape are integrated within the same object storage service, allowing internal data lifecycle management between disk and tape.


IceTier goals: Provide a standalone archival object store based on tape, integrate tape based object storage with disk based object storage.
